Upgrade your boating experience with a reliable thru-hull transducer designed for clear underwater imaging and precise navigation. Mounted directly through the hull, this model delivers consistent sonar performance without the drag or vulnerability of transom-mounted options. Anglers and boaters who demand top-tier fishfinding in various water conditions appreciate its dual-frequency capabilities and robust build.
This transducer combines dual beam technology with versatile frequencies to cover everything from shallow bays to deep offshore waters. The wide 74-degree beam at 200kHz excels in spotting fish and structure in shallower depths, offering detailed views up to 500 feet or more depending on conditions. Switch to the narrower 20-degree beam at 50kHz for deeper penetration, ideal for targeting trophy fish in 1,500 feet of water.
What sets it apart is the seamless integration with advanced charting systems, minimizing signal loss from hull interference. Boaters report cleaner bottom tracking and fewer dropouts during rough seas, making it a go-to for serious offshore trips.
Thru-hull mounting requires careful planning but pays off with superior signal quality. Select a flat hull section forward of the prop for minimal turbulence. Use marine sealant around the hull fitting to prevent leaks, and route the cable away from electrical noise sources like engines. For best results, fair the transducer face flush with the hull deadrise angle—many users pair it with adjustable fittings for deadrise up to 20 degrees.
Pro tip: Test in a bucket of water before final install to verify operation. This setup shines on planing hulls, delivering bubble-free sonar even at speed.
Engineered for high-end Humminbird displays, it connects effortlessly to ION and ONIX series units. For ION setups, ensure the Sonar Module is in place to unlock full potential. This combo powers detailed side imaging, down imaging, and 360 scans when paired right, elevating your on-water electronics stack.
Switch frequencies based on depth: 200kHz rules in 100 feet or less for spotting schools amid weeds, while 50kHz cuts through murkier deep water. Monitor temp breaks for walleye or stripers—the built-in sensor logs changes that predict bites. Regular cleaning with mild soap keeps the face crystal clear, extending transducer life through seasons of hard use.
Thru-hull models sit flush with the hull, avoiding prop wash and cavitation bubbles for cleaner sonar returns, especially at higher speeds. They're more protected from damage too.
The 74° wide beam scans a broad area for finding fish quickly, while the 20° narrow beam focuses on specific targets and bottom detail for accurate depth readings.
50kHz penetrates deeper for offshore use, up to thousands of feet, but with less resolution. 200kHz offers sharper images in shallower waters, great for inland lakes.
Yes, it has a built-in temp probe for surface water readings, typically accurate within 1-2°F, helping anglers locate thermal edges where fish congregate.
It's ideal for fiberglass and some aluminum hulls under 2 inches thick. Avoid on wood or steel without proper sealing to prevent corrosion.
ION series requires the Sonar Module for full compatibility—check your setup to ensure sonar processing is enabled.
Wipe the face gently after each trip, inspect cables for wear, and store dry in off-seasons. Avoid high-pressure washes that could damage seals.
